CSV Cleaner

About CSV Cleaner

CSV Cleaner standardizes messy CSV files: it trims stray spaces, removes blank and commented lines, normalizes headers, aligns column counts, and exports with your preferred delimiter, newline, and quoting rules.

What it fixes

• Inconsistent spacing around delimiters.
• Duplicate or poorly cased header labels.
• Rows with fewer or more columns than expected.
• Mixed newline styles across platforms.

Tips

• Enable “Align columns” and choose “Pad short rows” to safely keep data while fixing structure.
• Use a comment prefix to skip metadata lines (e.g., # or ;).
• Export with Quote all fields when you plan to import into strict parsers.
